Expression (n.) sometimes has to be taken out of the language and sent for cleaning before it can go back into circulation.
Expression (n.) consists in incalculability: if I knew exactly how he would grimace, there would be no facial expression — yet a piece known by heart keeps its gestures.
Expression (n.) that is crude and incorrect is still a living seedling, and the mediocre writer who replaces it too quickly with a correct one kills the original idea, which then shrivels and is no longer worth anything.
Expression (n.) is what really goes with speaking: modulation, timbre, accent, and nobody would dream of calling that thinking.
Expression (n.) may be put in place of the experience it expresses; they aren't the same, as a railway train and a railway accident aren't the same thing.
Expression (n.) is not translating an idea from a mental language already written into a verbal one; it is groping, rejecting words, until one comes and I say 'That is what I meant!'
Expression (n.) was, Wittgenstein said, the whole of his enormous difficulty in logic.
